This invention relates to button loops and more particularly to button loops capable of the lateral expansion of a part from which a substantially rigid member is suspended, the

button loop being adapted to connect a strap with a button carried by a garment, or the like, intended to be supported by the strap.

The objects of the invention are to provide 7 for an expansible button loop a suspended 10 rigid member maintained within the plane of the button loop and to provide for a button loop, button-receiving and button-retaining members relatively assembled by means of keyed bearings permitting the lateral expansion of one member but maintaining both members against relative pivotal movement; With these and other obj sets in view as may become apparent from the within disclosures, the invention consists not only of the particular form herein pointed out and illustrated in the drawing, but readily admits of certain modifications within the scope of what hereinafter may be claimed.

The device about to be described is an improvement upon a well known form of a twopiece button loop, such as is shown in the Howe patent, Number 961,718, granted June 14, 1910, in which the two pieces are so assembled that one piece may laterally eX- pand while both pieces are adapted for relative pivotal movement out of the plane of the device in both directions. It is apparently desirable to have the advantages of the Howe button loop in which the pivotal as sembly of the parts permits the lateral expansion of one piece, but it appears to be equally advantageous that both pieces be maintained in a common plane in order that overalls having such button loops may be stacked for shipment without fear that one piece of the button loop may be swung at right angles to the other piece and puncture the overall material. The applicant is aware of the patent granted to Hodge, September 9, 1930, Numi- 53 the improved button loop so forms these porber 1,7 75,100, in which a two-part button loop JOHN H.

device embodying the invention and illustrated by the figuresiin the accompanying drawing in which the Figure 1 is an upright elevation of the device in a normal'condition as regards the assembled pieces; the Figure 2 is a cross-section on the dotted line 2-2 ofthe previous figure; and the Fi ure 3 is an upright elevation of the device illustrating. 7

onepart laterally expanded the Figure 4 belng an upright elevation of afmodihed form of device, j j v Referring more particularly to the draw-r mg, the device as illustrated'is made "in two pieces, of which a middle portion of thc'wire' or the eXpansible member is formed :to' provlde the suspension loop 1 having the horizontal bar 2 around which a strap (not illus{ trated) may be looped'that the device maybe suspended from-a looped strap. Remaining end portions of the wire depend from the suspension loop 1 as spring arms 3 and 1 '-which cooperate to provide the button-re ceiving loop 5, the wire terminals beingouit-fi wardly looped to provide the terminal loops 6 and 7.in relative alignment one with the" other as illustrated by the Figures 1 and-'3, the terminal loops 6'and 7 providing the 're stricted portion 8,vadd af'mished"appearance to the member, and servelror another purpose about to be explained; The lower bar of each or" the terminal loops6 and 7 is flat tened in the plane of the member and thus provldes the shafts 9 which are rectangular incrosssection, as illustrated by the Figure 2. 'The other piece of the: deviceis substan-' tially rigid although it too may be made of.

resilient material if desired, This piece is formed to provide the button-retaining loop! 10 and its terminals are each flattened and formed to provide the journals or supports 11, each encompassing a shaft 9 in such a manner as to provide the fiat interior bearing surfaces 1:2 for engagement with the flat bearings surfaces 9 of the shaft 9. In this manner the shafts 9 in their engagement Within their respective journals or supports 11 are so keyed therein that only a relative sliding movement of the shafts 9 Within the journals or supports 11 is permitted.

The Figure 1 illustrates a shank S in cross-section Within the button-receiving loop in readiness to operate expandingly the restricted portion 8 of the expansible part of the device, the dotted position of the shank S illustrates the shank S seated Within the button-retaining loop 10 after having passed through the restricted portion 8. The Figure 8 illustrates the shank S Within the restricted portion 8, the expansible member being thereby laterally expanded to the position there shown Wherein the flattened shafts 9 have longitudinally moved in opposite directions Within the ournals or supports 11, the depending member being maintained in the plane of the device. The resiliency of the expansible member is relied upon to return the parts to their normal relative condition after the shank S has passed in one direction or the other through the restricted portion 8.

The Figure l illustrates a modified form of keyed relation between the two pieces of the device. The shaft 9A is left in cylindrical form of the Wire, and the journals or supports 11A are looped around the shafts 9A,

and the supports 11A are each provided With a key-slot 11B for the reception of a key-pin 11C provided by the end portion of the terminal loops 6A and 7A.

I claim:

, 1. A two-member button loop, one member comprising a button-receiving loop having a laterally expansible throat portion and depending terminals providing shaft portions in relative alignment With each other, the other member comprising a substantially rigid button-retaining loop having terminals providing journals for said shaft portions, the bearing surfaces of the shaft portions and journals being so formed as to permit only a longitudinal movement of said shaft portions Within said journals.

2. A two-member button loop, one member comprising a button-receiving loop having a laterally expansible throat portion and de pending terminals providing flattened shaft portions in longitudinal alignment, one With the other, the other member comprising a substantially rigid button-retaining loop having terminals providing journals for'said shaft portions, the shaft portions having flat bearing surfaces for engagement With the flat surfaces of the flattened shaft portions for a relative sliding movement, only, of the flattened shaft portions Within said journals.
